I don't think all robots need to be 1:1 replicas of humans but you might be underselling versatility. One robot for every specific task might be a good idea in some places where as in others it might be better to have robots capable of performing several types of tasks giving you the freedom to assign them to different roles as needed. It cuts down on the number of robots (and back up robots) you need to keep available. A more human form would allow for that versatility and allow for easier interaction with the world and the items within it which we've built with accommodation of our own bodies in mind. I am generally a fan of the 'do one thing and do it well' type of philosophy though and ideally we'll have a mix of specialized machines and general purpose ones.
